IBA Conservation

IBA conservation status - summary
Year of assessment (most recent) Threat (pressure) Condition (state) Action (response)
2009 very high not assessed low
Was the whole site assessed? no Condition (state) assessed by unset
Accuracy of information good

Threats to the site (pressure)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - agro-industry farming happening now some of area/population (10-49%) moderate to rapid deterioration high
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now whole area/population (>90%) slow but significant deterioration high
Biological resource use logging & wood harvesting - unintentional effects: subsistence/small scale happening now whole area/population (>90%) moderate to rapid deterioration very high
Energy production and mining mining and quarrying happening now some of area/population (10-49%) moderate to rapid deterioration high

Conservation actions taken at the site (response)
Protected-area designation Management planning Other conservation action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) No management plan exists but the management planning process has begun Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity low
